Abstract

The invention relates to a precision flat grinding method for large-diameter thin-walled parts, which includes: arranging a plurality of equidistant, equal-width and equal-depth grooves on a worktable or a magnetic conduction table of a grinder; attaching the large-diameter thin-walled parts needing flat grinding onto the worktable or the magnetic conduction table; performing flat grinding for the large-diameter thin-walled parts needing flat grinding; and the like. The precision flat grinding method solves the technical problem that parallelism of two end faces of each grinded part is ultra-poor as deformation of the parts at a front-end-of-line cannot be effectively eliminated during grinding by a conventional machining method at present. By the aid of the precision flat grinding method, deformation can be automatically corrected, and the parallelism of the two end faces of each part after flat grinding meets requirements.

Description

Large diameter thin wall machine parts'precise plain grinding processing method
Technical field
The invention belongs to field of machining, relate to a kind of method of processing parts, relate in particular to a kind of large diameter thin wall machine parts'precise plain grinding processing method.
Background technology
The design feature of rotary transformer stator pressure ring is that diameter is large, wall is thin, belongs to large diameter thin wall part, and part thickness is of a size of 1mm, requires to guarantee that the both ends of the surface depth of parallelism is within 0.01mm after plain grinding.According to producing statistics, each batch has 80% part self check defective adding man-hour, and wherein the defective reason of most of part is that the self check depth of parallelism is overproof, referring to Fig. 1.At present conventional processing method is directly part to be placed on the workbench of surface grinding machine to process, the major defect of this method is in grinding process, effectively to eliminate the distortion that part produces in preceding working procedure, causes part both ends of the surface depth of parallelism after grinding overproof.
Summary of the invention
In order to solve the above-mentioned technical problem existing in background technology, the invention provides that a kind of automatically calibrating part deforms and be the satisfactory large diameter thin wall machine parts'precise of the depth of parallelism plain grinding processing method of the both ends of the surface of the part after plain grinding.
Technical solution of the present invention is:
A large diameter thin wall machine parts'precise plain grinding processing method, its special character is: comprise the following steps:
1] a plurality of equidistant wide and grooves that groove depth is identical are set on the workbench of grinding machine or magnetic conduction platform;
2] will treat that plain grinding large diameter thin wall part is adsorbed on workbench or magnetic conduction platform;
3] treat plain grinding large diameter thin wall part and carry out plain grinding processing.
The width of above-mentioned groove is 1: 1~2: 1 with the ratio of flute pitch; The diameter ratio of the width of described groove and large diameter thin wall part is 1: 5~1: 15.
The cross section of above-mentioned groove is square, rectangle or circle.
Advantage of the present invention is:
1, to utilize dull and stereotyped smoothing principle that part is automatically carried out in process correcting deformed in the present invention, by the equidistant square groove wide and that groove depth is identical of processing on the workbench at grinding machine or magnetic conduction platform, solve the problem on deformation of part processing preorder, can automatic calibration distortion, make the depth of parallelism of part both ends of the surface after plain grinding reach requirement.
2, the present invention by adjust the width of groove and the ratio of flute pitch and, guaranteed that after plain grinding, the depth of parallelism of part both ends of the surface reaches requirement.
Accompanying drawing explanation
Fig. 1 is the structural representation of large diameter thin wall part;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is dull and stereotyped smoothing principle schematic;
Fig. 4 is large diameter thin wall machine parts'precise plain grinding process schematic diagram provided by the present invention;
Fig. 5 is the workbench of grinding machine or the structural representation of magnetic conduction platform;
Wherein: 1-large diameter thin wall part, 2-cushion block, 3-briquetting, 4-thin-walled is dull and stereotyped, the plain grinding head of 5-grinding machine, 6-workbench or magnetic conduction platform, 7-groove.
The specific embodiment
A large diameter thin wall machine parts'precise plain grinding processing method, comprises the following steps: 1] a plurality of equidistant wide and grooves that groove depth is identical are set on the workbench of grinding machine or magnetic conduction platform; 2] will treat that plain grinding large diameter thin wall part is adsorbed on workbench or magnetic conduction platform; 3] treat plain grinding large diameter thin wall part and carry out plain grinding processing.The width of groove is 1: 1~2: 1 with the ratio preferred version of flute pitch; The diameter ratio preferred version of the width of groove and large diameter thin wall part is 1: 5~1: 15.The cross section of groove is square, rectangle or circle.
The principle of the invention:
The present invention is directed to the poor main cause of these large diameter thin wall machine parts'precise grinding depth of parallelisms at present carefully analyzes, think that causing such result is mainly because part is larger in the distortion of front operation, when grinding, can not effectively eliminate the distortion of part, finally cause part depth of parallelism after processing overproof; Therefore, for the problems referred to above, for such part, carried out the analysis of process, and found the overproof main crux of the depth of parallelism, and tested out the best method of processing like parts, utilize dull and stereotyped smoothing principle (referring to Fig. 3) that part is automatically carried out in process correcting deformed, add the groove (referring to Fig. 4) that man-hour, processing was equidistant wide and groove depth is identical on the workbench of grinding machine or magnetic conduction platform, then part is inhaled and processed on workbench or magnetic conduction platform.
